CARBURETER.

Speccaticn of Letters Patent.

Patented Oct. 29, 1912.

Application filed September 29, 1911. Serial No. 651,977.

Yo all fic/wm 2'2( may concern Be it known that I, HERMAN VVALTHER, a citizen of the United States, residing at Davenport7 in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Carbureters7 of which the following is a specification, reference being had therein to the accompanying drawing.

rlhis invention relates to an improvement in carbureters and more particularly to an improved means for controlling the iiow of liquid from the gasolene storage chamber to the carbureting chamber.

The object of the present invention is the provision in a device of this character of automatic means for controlling the flow of gasolene from the gasolene storage chamber to the carbureting chamber of such a construction that lthe amount of liquid which is permitted to pass to the carbureting chamber may be readily controlled without the necessity of having access directly to the carbureting chamber.

A further object of the invention is the provision of improved means for controlling the flow of gasolene from the storage chamber to the carbureting chamber of such a construction as will prevent any danger of the gasolene freezing before passing into the carbureting chamber.

A further object of the invention is to provide a carbureter in which the valve which controls the passage of fluid from the storage chamber to the carbureting chamber' may be readily removed for the purpose of cleaning or repairing the same.

Other objects of the invention will be apparent from the detailed description hereinafter, when read in connection with the accompanying drawings forming a part hereof, wherein a convenient embodiment of the invention is illustrated and wherein like characters of reference refer to similar parts in the several views.

1n the drawings: Figure l is a vertical sectional view of a carbureter embodying the present invention; Fig. 2 is a fragmentary longitudinal section illustrating the construction of the pipe which connects the storage and carbureter chambers and the valve construction for controlling the flow of liquid through said pipe, and Fig. 3 is a cross section on line 3-3 of Fig. 2.

Referring now more particularly to the drawings, A designates a tank which is adapted to be placed under ground and which is provided with a horizontal partition A dividing the interior of the tank into an upper or gasolene storage chamber B and a lower or carbureting chamber C.

D designates the air supply pipe which projects into the carbureting chamber and communicates with an air distributing head D. which is adapted to be submerged 4below the level of the gasolene in the carbureting chamber. The air pipe and distributing head may be of any desired construction and as they form no part of the present invention7 I have deemed it unnecessary to describe t-he same in detail. Communicating with the upper portion of the carburet` ing chamber is a gas outlet pipe E which may be of any well known construction.

F designates a plug which 1s provided with a ange f intermediate the ends thereof, the lower end of which is fitted with an opening formed in the partition plate A. The lower portion of the plug F is threaded upon its exterior and said plug is rigidly clamped to the partition plate A by means of a clamp nut which is threaded upon the lower portion of the plug and serves to clamp the portion of the partition plate adjacent the opening therein firmly against the collar f of the plug. Threaded upon the exterior of the upper portion of the plug F is a vertically disposed tube G which projects upwardly through the gasolene storage chamber and the upper end of which extends into a suitable boX H which is positioned near the surface of the ground. A cap G is provided for the upper end of the tube G, which cap is removable so that access may be had to the interior of said tube. The lower end of the tube G is provided with a plurality of openings g in the wall thereof which are located just above the top of the plug F and which serve to permit gasolene to flow from the gasolene storage chamber B into the interior of the tube G. The lower portion of the plug F is provided with a counter-bore therein in which is threaded the upper end of a pipe I which extends downwardly into the carbureting chamber C, the lower end of said pipe being positioned above the normal level of the gasolene in said carbureting chamber and being provided with a plurality of serrations or notches z' therein. The plug F is provided with a cent-rally disposed vertical opening f2 therein and with a plurality of small vertically disposed ports f3 extending therethrough and arranged circumferentially about the opening f2. The upper surface of the plug F is provided with a concave portion f* with which the upper ends of the ports communicate and the upper surface of said plug is inclined downwardly from the central portion thereof to the periphery thereof to provide a sharp circular edge around the concave portion f4 which constitiites a valve seat.

Slidably mounted in the opening f2 which extends through the central portion of the plug F, is a valve rod K, the upper end of which projects above the top of the plug F and is rigidly connected in any suitable manner to a weight L which is positioned within the pipe G, and the lower end of which projects below the lower end of the pipe I and is threaded into the bottom of a cupshaped member M which embraces the lower end of the pipe I, the side walls of said cupshaped member being spaced from the outer surface of the pipe I. II`he lower end of the weight L is provided with a socket Z in which is removably seat-ed a valve Z of cork or other flexible material which is adapted to cooperate with the valve seat formed on the top of the plug F to prevent the passage of gasolene through the ports f3 when the valve is in its closed position.

Itigidly secured to the upper portion of the weight Il and extending upwardly in the tube G, is a rod L which terminates at its upper end in a handle L2 permitting rotation of the rod L', weight L, and valve rod K, for a purpose to be hereinafter more particularly set forth.

Formed rigid with the pipe I and projecting laterally therefrom, is a bracket N which is provided at its free end with a depending portion N to which is pivotally connected a lever 0 to the long arm of which is connected in any suitable manner, a float O. The lower portion of the cup-shaped member M is provided with a cleft therein in which is pivotally securedl in any suitable manner the short arm of the lever O.

In the operation of the device as thus described, as long as the gasolene in the car bursting chamber is maintained at the proper level, the valve Z will be held upon" its seat so that no gasolene will pass from the gaso-lene storage chamber to the carbureting chamber. 11s soon as the liquid in the carbureting chamber falls below its normal level, however, the float 0 will fall and the lever O will elevate the cup-shaped member M and the valve rod K, thus lifting the valve Z off its seat and permitting gasolene to flow from the pipe G through the ports 7f3 in the plug F, into the pipe I and cup -shaped member M. The cup -shaped member M will, as the float lowers, be brought into contact with the lower edge of the pipe I but the gasolene will flow into the carbureting chamber through the serrations z' formed in the lower end of the pipe I.

The time when the float O acts to cut olf the liow of gasolene from the gasolene storage chamber' to the carbureting chamber may be varied by adjusting the position of the valve Z relative to the cup member M. To effect this adjustment, it is only neces sary to remove the cap G from the upper end of the pipe G and rotate the handle portion L of the rod L to bring the lower threaded end of the valve rod K out of its threaded socket in the cup-shaped member to any desired extent. This is an important feature of the present invention as the amount of liquid which is to be maintained in the carbureting chamber must vary with the character of the fuel employed and the present construction enables the operator to regulate this amount to a nicety without necessitating his having access directly to the carbureting chamber.

'Io obtain the best results, it has been found desirable to feed the gasolene from the gasolene storage chamber to the carbureting chamber through restricted ports, but when the gasolene is fed directly into the carbureting chamber in this manner, it has been found that when the apparatus is used in extremely cold climates, the gasolene frequently freezes. With the present construction, this defect is overcome and all of the advantages incident to the feeding of the gasolene through restricted ports, have been preserved, as the gasolene is fed from the storage chamber through the restricted ports, but does not come in contact with the air until it passes through the serrations i in the lower end of the tube I and up be tween the outer wall of the tube I and the side wall of the cup shaped member, and the notches are made of such a size that when the gasolene finally comes in contact with the air, which is at the top edge of the cupshaped member, that there is a sufficient quantity of gasolene at this point to avoid any likelihood of the saine freezing.

While a convenient embodiment of the invention is illustrated in the accompanying drawings, it will be obvious that many changes may be made to the particular form and construction therein shown without departing from the spirit and scope of the invention as defined in the appended claims.
